Main Features

The VGA-3 guitar amp provides 50-watt output from a high-volume, 30-cm speaker housed in a portable cabinet. The unit features an advanced combination of core functions plus COSM technology for realistic V-Guitar amp sounds.

●COSM AMPLIFIER

The VGA-3’s amp modeling function reproduces the sounds of many popular guitar amps. This amp features eleven amp types including modeled amp sounds, from the delicate clean sound of the combo type to the large stack’s massive distortion sound, and also an original flat amp perfect for use with acoustic guitar and synthesizer sound.

●EFFECT

Including a newly developed spring reverb, the VGA-3 incorporates ten DSP effect types perfectly suited for use with guitar sounds.

●COSM GUITAR

In addition to the regular guitar input, this amp also features GK input for guitar modeling. Guitar modeling provides eleven realistic sound simulations, from electric and acoustic guitar sounds to special sounds available only with GK. Achieve a whole range of sound variations, without having to switch your guitar.

●MEMORY

The VGA-3’s memory lets you store and instantly call up ten amp and effect settings internally. Additionally, with the use of a foot controller (optional), you can store and call up forty settings.

●TUNER

A chromatic tuner is included.

●EXPANDABILITY

Not only can you connect a foot switch, the VGA-3 also provides an input for an expression pedal, which can be used as a volume pedal or wah pedal.

Also included are an EXT IN jack for connecting a CD or rhythm machine, and a RECORDING OUT/PHONES jack, which comes in handy for recording sessions or when practicing at home.
